Could I pay for Julia with 4*s? I have a few lv 40s that I would be trading and a few fresh.

I don't have any te cuz I can't get my 4*s to sell and I'm not allowed to spend money... But if you allowed me to pay with 4*s you could easily use them for enhancing and exchanging. I can also level break a few units or one unit a few times if you want as payment as well. I also have a tradeable potion and can partially pay with that.
